The character work is really good here, always a strong suit for the team of Palmiotti and Gray. Amnesia is usually a shortcut to avoid defining characters and circumvent sketchy motivations, but this is the best use of the plot device I’ve seen in a long time. Samantha’s attempts to deal with her lack of identity while insane things happen all around her lifts Book Smart beyond just being a fun action thriller.
I have to say, Book Smart made me actually laugh out loud twice. Once with the reveal of Samantha’s true identity, which was truly surprising but also made perfect sense with everything that had been established. The second time came near the end when the intelligence agencies of two different countries get into a gunfight over who gets to kill the heroes. As character-focused as the story is, the action scenes are deeply satisfying.
